Hmmm...I have a red led that goes on if I press the lock button on the fob a second time, it's mounted at the bottom of the dash. It has a tiny button on the reverse that I pressed but don't know what it does yet. Maybe a 'valet' button?
Does the black box have a big white sticker on the opposite side? I have a 2009 XLT.
